论拿破仑的政治生命与战争的关系

拿破仑是法国大革命时期名的资产阶级政治家和军事家。他一生活动的大部分是与军事紧密联系在一起的,战争使拿破仑登上了法国权力的顶峰、成为了欧洲大陆的霸主,但战争也使拿破仑结束了政治生命。这说明战争的性质决定着战争的胜负,也主宰着战争发动的政治生命。     

Statistical properties of nucleotide clusters in DNA sequences

Using the complete genome of Plasmodiumfalciparum 3D7 which has 14 chromosomes as an example, we have examined the distribution functions for the amount of C or G and A or T consecutively and non-overlapping blocks of m bases in this system. The function P(S) about the number of the consecutive C-G or A-T content cluster conforms to the relation P(S)oce-as;values of the scaling exponent αCG are much larger than αAT; and αAT of 14 chromosomes are hardly changed, whereas αCG of 14chromosomes have a number of fluctuations. We found maximum value of A-T cluster size is much larger than C-G, which implies the existence of large A-T cluster. Our study of the width function ξ(m) of cluster C-G content showed that follows good power law ξ(m)ocm-γ. The average γ for 14 chromosomes is 0.931. These investigations provide some insight into the nucleotide clusters of DNA sequences, and help us understand other properties of DNA sequences.     

大用户直购电对清洁发电和用电节能的影响探讨

目前,随着我国电力市场改革的逐步深入,大用户直购电模式正在试点展开,但该模式尚存在管理办法不完善等问题,实施后可能对发电企业清洁发电及电力大用户电力节能产生一定的影响。本文分析了大用户直供电模式对发电侧、电网侧和用户侧产生的影响,尤其是大用户直购电模式将会对发电企业的清洁化改造和用能企业的节能化管理造成的影响。结果表明院大用户直供电模式可以有效降低电力用户用电成本,提高发电企业盈利能力,但尚需完成相关政策法规等保证大用户直供电模式实施后的节能减排工作。     

‘Thrash yourself Thursday’: the production of the ‘healthy’ child through a fitness-based PE practice

Saturating the Canadian landscape are media and health industry discourses representing childhood physical ‘(in)activity’ and ‘obesity’ as being at ‘epidemic’ proportion. Increasingly identified as a focus of concern within such representations is the school setting, simultaneously positioned both as a cause of and a key institutional site for redressing these ‘pathologies’. Drawing on qualitative research carried out at a Canadian elementary school, this discussion offers a Foucaultian governmental analysis of one school's navigation of this gauntlet of accountability to improve children's health. Specifically, the school-wide fitness-based initiative known as ‘Thrash yourself Thursdays’, whose objective is the production of ‘healthy’ students, is examined to understand the power relations enacted through it, and how the target of this practice (i.e. the children) negotiated such efforts to shape their bodily conduct. This in turn, offers a unique contribution to the governmental literature, which is more characterised by attending to discourses and strategies of government rather than how the subjects of such strategies respond to such efforts.
